9.6 Module Dependent Factory Stores

A selection of Factory Stores have been created for various applications of the FireWire I/O
Module, they are described below.

9.6.1 Analogue to Digital / Digital to Analogue (+ Digital)

If your ADA-8 is fitted with a single FireWire I/O Module, the "FireWire AD/DA" store will
appear in the store banks when the Factory Stores are recalled. Use this store for common
A/D and D/A applications with sample rates up to and including 96kHz.
When this store is recalled the FireWire I/O Module is configured for 8 in / 8 out operation.
Giving a total of 8 input channels and 8 output channels.
If you have an ADA-8 XR and wish to use this store with sample rates above 96kHz, you can
do so by adjusting the FireWire I/O configuration to 4 in / 4 out as described in section 9.5.2.
The unit will operate as before, except that input and output channels 5 to 8 will not be active.
Path 1 is configured for analogue to digital conversion. The path synchronization source and
sample rate are controlled by the workstation. See sections 9.7 and 9.8 for further information
on controlling the ADA-8 from the workstation.
Path 2 is configured for digital to analogue conversion. The path is synchronized to the
FireWire I/O Module and the path sample rate is set to '=Ext'. These settings ensure that
Path1 and Path 2 are synchronous.
Note that if an AES3 I/O Module is also fitted to the ADA-8, Path 2 will be set up to use both
the analogue and AES3 outputs.

9.6.2 16 Channel Analogue to Digital

If your ADA-8 is fitted with two FireWire I/O Modules, and two Analogue Line Input Modules,
the "FireWire 2xADC" store will appear in the store banks when the Factory Stores are
recalled. Use this store for 16 channel A/D applications with sample rates up to and including
96kHz.
When this store is recalled each FireWire I/O Module is configured for 8 in / 2 out operation.
Giving a total of 16 input channels and 4 dummy output channels (the dummy output
channels are required to maintain synchronization between FireWire I/O modules).
Path 1 is configured for analogue to digital conversion. The path synchronization source and
sample rate are controlled by the workstation.
Path 2 is configured for analogue to digital conversion. The path synchronization source and
sample rate are controlled by the workstation.
See sections 9.7 and 9.8 for further information on controlling the ADA-8 from the workstation.

9.6.3 16 Channel Digital to Analogue

If your ADA-8 is fitted with two FireWire I/O Modules, and two Analogue Line Output Modules,
the "FireWire 2xDAC" store will appear in the store banks when the Factory Stores are
recalled. Use this store for 16 channel D/A applications with sample rates up to and including
96kHz.
